Hi WG, Authors,
Yes/Support (but I have some concerns, that can be addressed once the
document is a WG document)
(1) Strictness
a. The document suggest local policies to decide the computation
behavior, I would prefer to have normative text for better inter-operability. I
think this point was also discussed during the IETF meeting.
b. Also It would be helpful if we keep the proposal aligned to existing
PCEP objects and mechanism
i. SVEC
Flags (which are strict) [RFC5440]
ii. OF codes
(which allow maximizing diversity, with no strictness guarantee)
[draft-dhody-pce-of-diverse]
c. I would propose following encoding change
i. Single
disjoint association type (instead of 4)
ii. Add flags
in DISJOINTNESS-INFORMATION-TLV for node, link, srlg (similar to SVEC - strict)
iii. Add
OF-Code also in the TLV
(2) I am not sure about this text in the section 3 -
o Configuration: in case the PCC is performing the path computation
but the PCE (without computation engine) is managing the LSP
parameters, the PCE should add the disjoint-group within the
PCUpdate message to communicate to the PCC the disjointness
constraint.
* I don't think the use of PCUpd in this way would be aligned to the
Stateful PCE draft. Perhaps this needs to be discussed on its own.
(3) Some text should be added to suggest how this would work along with the
protection association draft
[draft-ananthakrishnan-pce-stateful-path-protection]. IMHO both association
group should be used together when we would like to specify the diversity
requirement of the protection LSP. Some text could be added here.
Based on the discussion with authors, I can provide text if required.
Regards,
Dhruv
